Energy and environmental analysis of flavonoids extraction from bark using alternative solvents
(Elsevier, 2021-05-04)
[EN] Tree barks are rich in extractive compounds, among which the flavonoids are considered as products of interest. Due to the increase in the demand for these natural products, the development of efficient and sustainable ...
Eco-friendly isolation and characterization of nanochitin from different origins by microwave irradiation: optimization using response surface methodology
(Elsevier, 2021-07-09)
[EN] The extraction of nanochitin from marine waste has attracted great industrial interest due to its unique properties,
namely biodegradability, biocompatibility and as a functional reinforcing agent. Conventional acid ...
Hyper-altruistic behavior vanishes with high stakes
(Public Library Of Science, 2021-08-25)
Using an incentivized experiment with statistical power, this paper explores the role of stakes in charitable giving of lottery prizes, where subjects commit to donate a fraction of the prize before they learn the outcome ...
Optimization of the extraction of galactoglucomannans from Pinus halepensis
(About De Gruyter, 2021-06-25)
The effectiveness of pressurized hot-water extraction conditions for obtaining galactoglucomannans (GGMs) from Pinus halepensis suitable for applications like coatings and films packaging was investigated. For this purpose, ...
Determining the likelihood of incidents caused by human error during dynamic positioning drilling operations
(Cambridge University Press, 2021-03-23)
[EN] The probability of a human-caused incident occurring during dynamic positioning (DP) drilling operations is
determined in this paper using binary logistic regression models built with data on 42 incidents that took ...
Addressing Linguistic Diversity in the Language Classroom in a Resource‐Oriented Way: An Intervention Study With Primary School Children
(Wiley, 2020-06)
Adequately responding to linguistic diversity in the classroom is imperative in European school contexts, not least because of current migratory movements. This article presents the results of an intervention study with ...
Type 2 diabetes mellitus alters cardiac mitochondrial content and function in a non-obese mice model
(Academia Brasileira de Ciencias, 2020)
Type 2 diabetes mellitus (T2DM) is associated with an increase of premature appearance of several disorders such as cardiac complications. Thus, we test the hypothesis that a combination of a high fat diet (HFD) and low ...
The Anthropocene: Comparing Its Meaning in Geology (Chronostratigraphy) with Conceptual Approaches Arising in Other Disciplines
(American Geophysical Union, 2021-03)
The term Anthropocene initially emerged from the Earth System science community in the early 2000s, denoting a concept that the Holocene Epoch has terminated as a consequence of human activities. First associated with the ...
Data-driven nonparametric Li-ion battery ageing model aiming at learningfrom real operation data – Part A: Storage operation
(Elsevier, 2020-08)
Conventional Li-ion battery ageing models, such as electrochemical, semi-empirical and empirical models, require a significant amount of time and experimental resources to provide accurate predictions under realistic ...
Photoluminescent Coordination Polymers Based on Group 12 Metals and 1H-Indazole-6-Carboxylic Acid
(MDPI, 2021-03-22)
Two new coordination polymers (CPs) based on Zn(II) and Cd(II) and 1H-indazole-6-carboxylic acid (H2L) of general formulae [Zn(L)(H2O)]n (1) and [Cd2(HL)4]n (2) have been synthesized and fully characterized by elemental ...
